In other embodiments, network 105 may comprise one or more of a number of different types of networks, such as, for example, an intranet, a local area network (LAN), a wide area network (WAN), a wireless network, a Fibre Channel-based storage area network (SAN), or Ethernet. Other networks may be used. Alternatively, network 105 may comprise a combination of different types of networks.

Online document processing service 130 provides document processing services to users via network 105, enabling users to create, display, and edit documents remotely. For example, online document processing service 130 may provide online word processing services, allowing users to create, store, and edit text documents and other types of documents. Online document processing service 130 may be accessible via a World Wide Web page that may be viewed using a conventional Web browser, for example. A user may be required to log into a respective user account to access his or her document(s). Online document processing service 130 may offer common word processing features such as text editing, text searching, table creation and editing, etc. Online document processing service 130 may also provide other functions such as image creation and editing, spreadsheet management, etc. Online document processing service 130 may grant to a user access rights with respect to a document, such as viewing and editing rights.

User device 160 may be any device that enables a user to communicate via network 105. User device 160 may be connected to network 105 through a direct (wired) link, or wirelessly. User device 160 may have a display screen (not shown) for displaying information. For example, user device 160 may be a personal computer, a laptop computer, a workstation, a mainframe computer, etc. Alternatively, user device 160 may be a mobile communication device such as a wireless phone, a personal digital assistant, etc. Other devices may be used.

FIG. 2 shows functional components of an exemplary user device 160 in accordance with an embodiment. User device 160 comprises a web browser 210 and a display 270. Web browser 210 may be a conventional web browser used to access World Wide Web sites via the Internet, for example. Display 270 displays documents, images, Web pages, and other information to a user. For example, a text document that a user creates or edits may be displayed on display 270.

FIG. 3 shows functional components of online document processing service 130 in accordance with an embodiment. Online document processing service 130 comprises a document process 310 and a document repository 325. Document process 310 manages documents and performs operations requested by users, such as creating documents, editing text, performing text searches, etc. Documents created by users are stored in document repository 325. A document created by a user may be stored in association with his or her user account, for example. Multiple versions of a user's document may be stored in document repository 325. Document process 310 also provides comment and discussion functions allowing users to generate comments relating to documents, and to participate in discussions relating to documents. Information relating to comments and discussions may be stored in document repository 325.

In accordance with the embodiment of FIG. 1, a user may access online document processing service 130 and create and/or edit a document. For example, a user may employ browser 210 to access a World Wide Web site maintained by online document processing service 130. In a well-known manner, the user may be required to log into a user account to access his or her documents. The user may be required to authenticate his or her identity, e.g., by entering a user name and password, before accessing his or her user account and documents associated with the account. Online document processing service 130 may verify the user's access rights with respect to a document before granting the user access to the document.

Suppose, for example, that a first user, employing user device 160-A, accesses online document processing service 130 and creates a new document, such as document 400 illustrated in FIG. 4. In the illustrative embodiment, document 400 comprises text, including paragraphs 410 and 420. In various embodiments, a document may comprise lines of text, images, tables, headers, footers, footnotes, etc. Online document processing service 130 stores document 400, or data representing document 400, in document repository 325, as shown in FIG. 3. Online document processing service 130 may store a document model representing document 400, for example. The user may subsequently employ user device 160-A, or another device, to access document 400 via the Internet.

A well-known technique used by online document processing services to display a document on a user device includes transmitting data adapted to cause the user device to display all or a portion of the document on a Web page. For example, online document processing service 130 may transmit to browser 210 a request, in the form of HyperText Markup Language (HTML), adapted to cause browser 210 to display a representation of document 400. In response, browser 210 displays a representation of all or a portion of document 400. Suppose, for example, that after the first user creates document 400, a second user employs user device 160-B and accesses online document processing service 130 in order to view document 400. Online document processing service 130 transmits to user device 160-B data adapted to cause the user device to display a portion of document 400 on display 270, as shown in FIG. 5. In this illustrative embodiment, a page 560, including paragraphs 410 and 420, is displayed. Browser 210 also displays a toolbar 515 including various options, such as File option 517, and a scroll bar 592 that allows a user to scroll up or down within document 400.

In accordance with an embodiment, multiple comments relating to a particular document, received from one user or from multiple users, may be displayed simultaneously with the document on the display of a user device. FIG. 6 is a flowchart of a method for providing online document services in accordance with an embodiment. At step 610, a plurality of comments associated with a document is received. At step 620, a representation of the document and a representation of a comment thread comprising the plurality of comments is caused to be displayed simultaneously on a user device.

Suppose, for example, that while viewing document 400, the second user wishes to add a comment relating to paragraph 410. In an embodiment, the second user may select an option to add a comment. Referring to FIG. 5, for example, the second user may right-click on a computer mouse to cause a menu of options to appear on display 270. In response, online document processing service 130 causes browser 210 to display a menu 540 including an “Add Comment” option 552. When the second user selects Add Comment option 552, browser 210 transmits the selection to online document processing service 130. In response, online document processing service causes browser 210 to display a region in which the user may compose a comment. Referring to FIG. 7A, browser 210 may display page 560, including paragraphs 410 and 420, in a left-hand portion of display 270, and display, in a right-hand portion of the display, a comment box 720 in which the second user may compose a comment. Comment box 720 comprises an image 752 or other representation of the second user, and an indication 756 of the second user's name, nickname, username, title, etc.

After the second user composes a comment within comment box 720, the second user may either post the comment, by selecting an add option 777, or may choose to cancel the comment, by selecting a cancel option 788. In the illustrative embodiment, the second user selects add option 777. Browser 210 transmits the selection, and the second user's comment, to online document processing service 130. In response, online document processing service 130 stores the second user's comment in document repository 325, as comment 791, as shown in FIG. 3. In the embodiment of FIG. 3, online document processing service 130 defines a comment thread 802 associated with document 400, and stores comment 791 in association with comment thread 802. As used herein, the term “thread” means a data structure comprising information relating to one or more associated comments. In one example, various related comments in a thread may be stored at various memory locations within document repository 325, and the comment thread may comprise pointers to the various comments. FIG. 7B illustrates comment thread 802 in accordance with an embodiment. Comment thread 802 comprises a pointer 767 associated with comment 791, for example. A comment thread may comprise other types of information. Other data structures, such as a database, may be used to define and/or store a comment thread.

Online document processing service 130 transmits to user device 160-B, and to other user devices, data adapted to cause the user device to display simultaneously a representation of document 400 and a representation of comment thread 802. In response, browser 210 may display, on display 270, a page such as that shown in FIG. 8. Page 560 of document 400, including paragraphs 410 and 420, is displayed in a left-hand portion of display 270. Comment thread 802, including the second user's comment 791, is displayed simultaneously in a right-hand portion of display 270.

As indicated in FIG. 8, a reply option 875 is displayed in association with comment thread 802. Reply option 875 allows a user to reply to comment 791 or otherwise to add an additional comment to comment thread 802.

After the second user's comment 791 is received and posted, as discussed above, additional comments may be received from other users. Suppose, for example, that a third user, employing user device 160-C (shown in FIG. 1), views document 400, and comment 791, and wishes to add a comment in reply to comment 791. The third user may select reply option 875, using a computer mouse, for example. Browser 210 transmits the selection of reply option 875 to online document processing service 130. In response, online document processing service 130 transmits to user device 160-C data adapted to cause the user device to display a comment box allowing the third user to compose a comment. For example, online document processing service 130 may transmit a request that browser 210 display document 400 and comment thread 802 simultaneously, and that browser 210 include an additional comment box in association with comment thread 802. In response, browser 210 may display, on display 270 of user device 160-C, a web page such as that shown in FIG. 9. Page 560 of document 400, including paragraphs 410 and 420, is displayed in a left-hand portion of display 270. Comment thread 802, including the second user's comment 791, is simultaneously displayed in a right-hand portion of display 270. In the illustrative embodiment, a comment box 965 is displayed in which the third user may compose a reply comment.

In the illustrative embodiment, the third user composes a reply comment and selects add option 777. User device 160-C transmits the third user's selection, and the third user's comment, to online document processing service 130. Online document processing service 130 stores the third user's comment in document repository 325, as comment 1015, as shown in FIG. 3. Online document processing service 130 also updates comment thread 802 to include a pointer 768 (and/or other information) associated with the third user's comment 1015, as shown in FIG. 7B. Online document processing service 130 may then transmit to user device 160-C (and to other user devices) a request to display simultaneously document 400 and updated comment thread 802. In response, browser 210 displays, on display 270, a page such as that shown in FIG. 10. Page 560 of document 400, including paragraphs 410 and 420, is displayed in a left-hand portion of display 270. Comment thread 802, including the second user's comment 791 and the third user's comment 1015, are displayed within comment thread 802 in the right-hand portion of display 270.

Enabling users to maintain comment threads associated with a document, and displaying the comment threads simultaneously with the document, as described herein, provides particular advantages in the context of document production and management. Allowing users to view comments in real-time along with the document improves communication among users, provides a more efficient workflow and accelerates document production.

Referring to FIG. 10, a resolve option 1033 is also displayed in association with comment thread 802. In accordance with an embodiment, when a user selects the resolve option, comment thread 802 is removed from the display on each user's device, and is no longer displayed in association with document 400. However, comment thread 802, and the associated comments, remain stored in repository 325 and may be re-opened by a user at a later time. For example, if a particular user selects resolve option 1033, document processing service 130 may transmit a resolve notification message to one or more users associated with document 400 indicating that a user has selected the resolve option. For example, a resolve notification message may be transmitted to all users associated with the comment thread. Upon receipt of a resolve notification message, a user device 160 may display a message such as message 1122 shown in FIG. 11. In this example, notification message 1122 states that “A user has resolved this comment thread.”

Each recipient of the resolve notification message is provided an option to object to the resolution of the comment thread. Referring to FIG. 11, for example, notification message 1122 includes an “OK” option 1138 which a user may select if he or she agrees with the resolution of the comment thread, and a “Re-Open Thread” option 1165, which the user may select if the user does not want the thread to be resolved. If a user selects Re-Open option 1165, comment thread 802 is re-opened and continues to appear on display 270 in association with document 400.

In accordance with another embodiment, a first user may include in a comment an address associated with a second user. The inclusion of the second user's address in the comment causes a message to be generated and sent to the second user. Referring to FIG. 12, suppose that the first user reviewing a page 1227 of a document selects a comment option (in the manner described above) to add a comment associated with a particular paragraph 1274. In response, document processing service 130 displays a comment box 1282.

FIG. 13 is a flowchart of a method of providing electronic messaging services in accordance with an embodiment. In the illustrative embodiment of FIG. 12, a first user composes a comment in box 1282, and includes in the comment an email address 1286 associated with another user, “User5.” In the illustrative example of FIG. 12, the first user types “@user5@add1,” which includes a selected symbol “@” followed by a string of alphanumeric characters representing an email address of User5. It is to be understood that the alphanumeric characters used above to represent an email address are representative only, and that other characters, symbols, and formats may be used.

In one embodiment, when a comment box is displayed and a user is composing a comment, the alphanumeric characters typed by the user within the comment box are monitored, and when the “@” symbol is detected, a list of addresses associated with the document is displayed to the user. For example, a list of email addresses of other users associated with the document may be displayed. The user may select one of the displayed addresses for inclusion in the comment.

At step 1310, a comment relating to a document is received from a first user. When the first user indicates that the comment is complete, by selecting add option 777, for example, document processing service 130 receives the comment from user device 160, establishes a comment thread, if necessary, and adds the comment to the comment thread, in the manner described above.

At step 1320, an address is identified within the comment. Accordingly, document processing service 130 examines the first user's comment and determines that the first user's comment includes the email address “user5@add1,” associated with User5. At step 1330, a message is transmitted to the address. Document processing service 130 generates an email message and transmits the message to the email address “user5@add1.” The email message may notify User5 that a comment has been posted that includes the email address associated with User5, for example. The email message may also include a copy of the first user's comment. The message may include other information. For example, the email message may include a link that enables the recipient of the message to click on the link and post a reply to the first user's comment. Clicking on the link may cause the recipient's user device to connect to document processing service 130, access the document, and display the first user's comment and a relevant portion of the document, for example. While in the illustrative embodiment an email address is included in a comment, in other embodiments, other types of addresses may be used.

In various embodiments, the method steps described herein, including the method steps described in FIG. 6 and/or 13, may be performed in an order different from the particular order described or shown.
